Harmonic Sliver staples a repeating artifact and enchantment removal trigger onto every Sliver that enters the battlefield — including itself — which means a single copy can blow up multiple permanents in one turn if you're flooding the board. The cost is symmetry: opponents get the trigger too, so you run it because you're the one with nineteen Slivers and they're the one with a Smothering Tithe.

The First Sliver
The First Sliver cascades off every Sliver cast, which means Harmonic Sliver doesn't just answer one artifact or enchantment — it chains into the next Sliver, which triggers another Harmonic Sliver hit, turning a single spell into a wrecking ball across the table's problem permanents.

Commander is where Harmonic Sliver does its best work: artifact and enchantment hate is perpetually relevant, Sliver tribal is a supported archetype, and the symmetry drawback shrinks when you're the deck with the most creatures on board. In Legacy and Vintage, it sees essentially no play — those formats move too fast for a 1/1 body that asks you to build around it, and spot removal for artifacts exists on cheaper, more flexible cards. Modern is legal but similarly uninterested; Slivers as a tribe have a fringe aggro shell there, and Harmonic Sliver's utility trigger competes with slots better used on clock.

unknown tier
Pricing data isn't available at the moment — check Scryfall or your preferred vendor for a current number. Harmonic Sliver has been reprinted in a couple of Sliver-heavy products, so copies tend to be accessible rather than scarce; if you're building Slivers, this is unlikely to be the card that breaks your budget.
